WINDOW CONTROL AND SILENCER.

Application filed January 11, 1928. Serial No. 80,457.

This invention relates to a window control and silencer, and has special reference to that class of devices especially designed for the doors and bodies of automobiles, truck cabs, car windows and such places where a pane of glass, sash or other closure member is adapted to be adjusted primarily for ventilating purposes. My device may also be classified with those lifting devices wherein the retractile force of a spring is utilizedfor lifting or'closing a pane of glass or closure member which is adapted to be manually opened.

My invention, in its broadest aspect, involves a compact and durable device that may be easily and quickly mounted in the other structure for automatically lifting a ane of glass, sash or closure member that is slidable in the door, wall or structure and is adapted to completely close an opening in the door, wall or structure.

My invention aims to provide a window control and silencing device wherein a spring motor is utilized for lifting a pane of glass or other transparent material to a closed position, and associated with the spring motor is a control mechanism that may be characterized in the following particulars.

First, the control mechanism includes an anti-rattling device by which the pane of glass is clamped in any position to which it may be adjusted, so that the glass cannot rattlein-its frame or sash and is more or less cushioned against breakage incident to vehicleoperations.

Second, the control mechanism includesa brake-for the springmotor with the brake operable in synchronism with' the antirattling device so that there may be a cooperation of the brake and anti-rattling device for positively holding the pane of glass against accidental movement and the spring motor against accidental operation. I

. Third, the control mechanism includes means by which an initial opening movement may be imparted to the pane of glass so that it may beconveniently gripped and further manually opened, such operation placing the spring motor in active condition for instant use when it is desired to close the pane of glass.

There are certain novel structural details entering into my invention and these will be:

hereinafter specifically described and then claimed. Reference will now be had to the portion of the control mechanism relative to. a bottom rail of the pane .of glass;

Fig. 4 is a perspective view of a spring motor showing a cam member in a clamping position;

Fig. 5 is a vertical sectional view, on an enlarged scale, of a portion of the door show ing the control mechanism and silencer, with the mechanism in a clamping osition;

Fig. 6 is a detail sectional new of the portion of the control mechanism relative to the bottom rail of the pane of glass;

Fig. 7 is a plan of the control mechanism removed from the door;

Fig. 8 is a diagrammatic view of a cam member illustrating its functions, and

Fig. \9 is a detail sectional view of a portion of the control mechanism relative to the bottom rail of the pane of glass showing the manner. in which the pane of glass is held in a raised closed position.

In the drawings. the reference numeral 1 denotes a door, wall or other structure having a well 2 and an opening 3. The door has its top and bottom rails provided with grooves or ways 4 and aim the top and side edges of a pane of glass 6, sash or closure member which is slidable in the door frame and shiftable in and out of the well 2, the pane of glass when raised providing a transparent closure for the opening 3.

For the convenience of illustration and to somewhat conform to modern ractice. the

door 1 has been shown as ma e of metal,

with a slotted sill 7. through which the pane of glass 6 may be shifted. The inner wall 8 of the door has been shown as provided with an opening 9 for the convenience of mstalling my controlling mechanism in the well 2, the opening 9 being closed by door interior trimmings (not shown). It is to be understood, however, that for other t pes of doors and installations of my mec anism that it may not be necessary to provide the opening 9 nor the specific fastening'means which I employ for retaining the mechanism within the well 2.

The reference numeral 10 denotes a supporting plate which may be stamped and pressed to form a cylindrical casing 11 for a spring motor, and said plate 1s cut and stamped, as at 12 to rovide outstruck hook shaped lugs 13 whic 'may be mounted in openings provided therefor in the door wall 8, above the opening 9, which is adapted to receive the supporting plate 10 and permit of said plate being shifted up into the well and suspended by the hook shaped lugs 13 against the inner face of the door wall 8. Fixed within the casing 11 is a stud 14 and rotatable on said stud and shiftable longitudinally thereof is the hub portion 15 of a drum 16 having a single side wall affording an annular brake engaging surface 17. The periphery or rim 18 of the drum 16 has an annular flange or shoe 19 adapted to frictionally bear against the inner face of the door wall 8 and retard rotation of the drum. The rim' 18 has two transverse slots 20 and 21. Anchored in the slot 20 of the rim is the end 23 of a coiled band spring 24 which has its inner end anchored, as at 25, on the stationary stud 14, so that the spring may be coiled about the stud when the drum 16 is revolved in a spring winding direction. The spring 24 and its drum 16 constitute a spring motor enclosed by the casing 11 in cooperation with the door wall 8.

Anchored in the transverse slot 21 of the drum rim 18 is the end 22 of a flexible lifting member 26, preferably in the form of a strap wound on the drum with the outer end of the strap extending through an opening 27 provided therefor in the casing 11. The outer end of the lifting member 26 is suitably attached, as at 28 to the lower end 29 of an angularly disposed arm 30, said arm being disposed in a lateral direction to one side of the member 26 andin an outward direction towards the pane of glass 6. The upper end of the arm 30 is spot welded or otherwise secured to a channel rail 31 mounted on the lower end of the pane of glass 6, and said channel rail is pro vided with an outstruck lock lug 32 for a purpose that will hereinafter appear. The pane of glass 6 may be cushioned within the channel'rail 31 and said channel rail has a rolled edge 33 and an outstruck ledge 34.

The casing 11 is formed with a bearing or hous" 35 for an arbor 36 which may be partia y rotated or rocked in the hearing 35, said arbor extending through an oblong opening 37 in the doorwall 8 and having its outer end'provided with a detachable crank or hand piece 38 by which the arbor may be conveniently rocked. In addition to the arbor being rotative in its bearing, it is reciprocable with such longitudinal play of the arbor for a purpose that will hereinafter appear.

Mounted on the inner end of the arbor 36 is a cupped cam member 39 having a cam surface 41. The opposite flat face cam member .39 is adapted to engage a brake member 42 loosely mounted in an opening 43 provided therefor in the casing 11, and said brake member bears against the brake surface 17 of the drum 16 so that said drum may be-crowded towards the door wall 8 and clamped between the brake member 42 and the door wall. The brake member 42 will have a braking action against the drum 16 and the annular shoe 19 of .said drum will have a braking action against the door wall 8 which beingstationary will retard and cause the cessation in the operation of the spring motor whenthe brake member 42 is actuated.

The casing 11 is provided with two holders 43 and 44, both preferably outstruck from the wall of the casing 11. In addition to these holders there is a set of outstruck guide lugs 45 which cooperate with the holder 44 in correctly positioning a clamping member 46 relative to the casing 11 and the pane of glass 6. Adjacent the lower end of the clamping member 46 is a bowed portion 47 engaged by a comparatively fiat compression spring 48 suitably mounted in the holder 43 and this spring is adapted to hold the clamping member 46 in a retracted position, that is, normally in engagement with the cam member 39. The upper end of the clamping member 46 is also bowed, as at 49 and provided with a yieldable or friction shoe 50, made of leather, rubber, felt or any suitable material, that may be conveniently retained on the clamping member 46 by outstruck lugs 51 of said member. The shoe 50 serves functionally as a buffer and engages the inner face of the pane of glass 6, as best shown in Fig. 5, to hold the outer face of the pane of glass against a stationary buffer 52 carried by a bracket 53 attached to the under or inner side of the sill 7 The two buffers cooperate as a silencer or anti-rattling device to prevent the pane of glass from vibrating in its frame or sash, and these bufl'ers also serve as braking or clamping means for retarding movement of the pane of glass and holding it in adjusted position.

The cam member 39 is adapted to engage a pressed out portion or boss 54 on the upper inner face of the clamping member 46, and said cam member is formed with a peri heral crank 55 having an antifrictional roller 56 adapted to engage the ledge 34 of the sash rail 31, as best shown in Fig. 7. The cam member 39 has another portion in the form of a stop lug 57 adapted to engage the casing 11, as best shown in Fig. 4, said stop 111 being connected by a coiled retractile spring 58 to the supporting plate 10.

When the pane of glass 6 is fully raised or closed the flexible lifting member 26 is almost in an unwound condition on the.

spring motor and to a great extent the force of the spring 24 has been expended, yet retaining suificient retractile force to hold the lifting member 26 partly wound about the drum 18 with the upper edge of the pane of glass 6 in the upper groove or way 4 of the door frame.

Considering the position of the arbor 36,

as shown in Fig. 5, where the pane of glass is in a clamped position and the cam member 39 engaging the boss 54 of the clamping member 46 forcing the shoe 50 against the pane of glass 6 and said paneof glass against the buffer 52. In addition to this clamping action of the pane of glass there is the clamping action for the spring motor which is brought about by the brake member 42 bearing against the drum 16 and said drum against the door wall 8. In other words, the shoe 50 engaging the pane of glass 6 holds the boss 54 so that the cam member 39 may be wedged bet-ween the boss 54 and the brake member 42. This is permissible by reciprocable cam supporting arbor 36, and theposition of the cam member 39 is defined by the stop lug 57 engaging the casing 11, as shown in Fig. 4.

When it is desired to lower the pane of glass 6 from a full closed position and place it in a partly lowered posltion, as in Fig. 5, the crank or hand piece 38 is gripped and turned in a counterclockwise direction considering Fig. 8. Such rocking of the arbor permits retraction of the clamping member 46 under the influence of the spring 48, but the force of the spring is not suflicient to effect braking of the spring motor and simply retains the boss 54 in engagement with the cam member. As the cam member is rotated the spring 58 is stressed, the clamping member 46 releases the pane of glass 6 and it is to be noted that the anti-' frictional roller 56 is in engagement with the ledge 34 of the bottom rail 31 of the pane of glass, so that as the cam member 39 is rotated by the arbor 36 the pane of glass to be initially moved a redetermined distance. This has been indicated in Figs. 1 and 2, by the dash lines representing the pane of glam 6 as partially open and the gap or opening between the upper edge of flipped clockwise the pane of glass 6 and the door frame 1 is of sufiicient area to permit of a handgripping the upper edge of the pane of lass to ower it in the frame. The initia movement of the pane of glass has not conditioned or materially wound the spring motor, so the hand ma be removed from the hand piece 38 and p aced on the upper edge of the pane of lass tolower it to a full open position. uch adjustment will wind and condition the spring motor. The retractile force of the spring 58, restores the cam member 39 to a normal tion, and as the lowered position, t per edge of the 1ty to the han or neutral posi- Eane ofglassreaches a e same hand on the up- (glass is brought in proximpiece 38 which may be to cause the cam member 39 to actuate the clamping member and the brake member 42 whereby the pane of glass and the spring motor are held.

Reverting to the'lowering-movement of the pane of glass 6, the flexible lifting mem ber 26 is unwound ,from the drum 18 of the spring motor and the spring 24 is wound up, tius placing the spring motor in condition for activity when the pane of glass 6 is to be raised.

The arbor 36 and the drum 18 are reciprocable relative to the bearing 35 and the stud 14 respectively, so that the cam member 39 may wedge itself between the boss 54 and the brake member 42 while the drum 18 engages the door wall 8 for a braking action.

The cam member 39, as shown in Fig. 8, is designed so that a clampin portion 40 of the cam surface is engagea le with the boss 54 for holding the pane of glass lowered or in any intermediate sition. When the cam member 39 is turn in a clockwise direction, after the pane of glass is raised and in a closed position, the boss 54 engages a locking portion 54 of the cam. The clamping member 46 is shifted against the action of the spring 48 and the shoe 50 placed against the back lug 32 of the rail'31- and under said rail, so that the pane of glass is locked in a closed position. This is accomplished without the boss 54 reaching the peak of the cam surface, the portion of the cam being for any inequalities of manufacture or difference of thickness of the pane of glass. Obviously thepane of glass cannot accidentally lower or rattle on account of the combined locking and clamping action of the clamping member 46.

It will be noted that the pane of glass must be fully lowered before being placed '.ment of the cam member are optional with a manufacturer to meet a desired condition or modus operandi. 4

From the foregoing it will be observed thatthe greater part of my mechanism 15 made from sheet metal stampings and is a bench assembled structure that may be easily and guickl installed relative to a closure that is to e adjusted and clamped 1n adjusted. position, but while the parts have been shown in their preferred form as successively used, yet it is to be understood that the structural elements are susceptible to such changes as are permissible by the appended claims.
